SPECIFICATION forming part of Letters Patent No. 394,073, dated December4, 1888.

Application tiled January l0, 1887. Serial No. 223,978. (No model.)

To aZZ 14u/"1,0711, it may concern:

Be it known that `I, GEoReE N. KENvoN, a citizen of the United States,and a resident of Narragansett Pier, in the county ot' lVashingt0n andState oi' Rhode Island, have invented a new and useful Improvement in)leans for Unloading l'larges, ot which the t'ollowing is aspecitication.

Hereto'lore in unloading barges laden with coal, grain, d'c., it hasbeen the practice to raise the said material to the whart' in bucketsoperated by means ot' a stationary steamengine located upon the wharf;but on account ot the vast amount ot' such freight to be transported andunloaded it is highly desirable to secure a more rapid and econmnicalmeans t'or unloading such n'iaterials trom the barge in which it isshipped; and my invention consists in the improved construction of thebarge, whereby the same is adapted to unload its cargo from an inclinedrailway, as hereinafter fully set torth.

Figure l is a longitudinal section ot' the barge, showing the screws torraising the inner portion ot' the supplemental decks. Fig. 2 istransverse section ot' the same. Fig. 3 is an enlarged detail transversesection. Fig. -t is a detail view showing the screw and pivoted nutwhich serve to support the inner portion of the snplilemental deck.

The movable supplemental decks ll ll ot the liarge rest at their outeredges upon the main deck I, and are supported at their inner portions bymeans ot' the duplicate series of screws .l .l .I and the pivotally-heldnuts l( K K, which are secured to the under side ot the supplementaldecks by means ot' the bearingl pieces or straps L Il, the nuts K. beingprovided at their opposite sides with the pintles 'r r. The screws .lare held at their lower ends in a step, M, and are each provided with aworm-gear, M', which engages with the worm N upon the sha'tt 0, whichextends t'rom end to end ot' the barge and which is to be supported insuitable liiearings. Movement ot' rotation lis imparted to the shatt Otrom either end ot' the barge by meansot thehaml-whecls or capstans l),which are operatively connected to the shait O by means ot' bevel-gearsT, thus causing the supplemental decks H H to be raised or loweredsimultaneously, upoil the proper moven'ient ol' the hand-wheel, the

Screws ot' one longitudinal series being provided with a ri ght-handthread and the screws ot the` opposite series with alett-hand thread,

in order that with the same operating-worm N the decks ll II may bemoved simultaneously in the same direction.

The screws .l .I are so connected to the step M, by means of a roundedend, or otherwise, 6o

as to allow the required lateral movement ot their upper ends with theangular movement ot' the decks ll ll. lipon thc screws .ll .Iv areloosely placed the covers Q, which serve to prevent the ingress ol' water through the slot- 65 openings q in the main-deck l into the hold le'.A hinged or yielding cover, is also arranged longitlulinally ot' thesupplemental decks II ll, which serve to cover the variable opening'between the inner edges ot' the said 7o deck s, and the said cover Yma)- be provided with slots s, adapted to receive the projecting endsoi' the screws .l .l1

In loading the barge, the decks ll Il may be brought by means olil thescrews to the level ot the main deck I, and when it is desired to dumpthe load which has been placed upon supplemental decks the said decksare to be elevated to the proper inclined position by the requiredmovement ot' the screws, until 8o the load placed upon the deck willslide by gravity into the receiving-bin.

I claim as my invention- 1. The barge In'ovided with an adjustablesupplemental deck formed Ain two opposite parts, which have a pivot ortulcrum upon the mainaleck at eaeh side ot' the barge, in combinationwith the screws and nuts tor raising or lowering the inner portion ot'the supplemental deck7 and the cover which serves to 9o The bargeprovided with an adjustable supplemental deck formed in two oppositeparts, which have a pivot or fulcrum upon the main-deck at each side ofthe barge, in conibination with the duplicate series ot' screws forraising or lowering the inner portion oi Ioo the supplen'iental deck,the centrally-arranged shaft for connectedly turning the series oiscrews, the series of worms secured to the central shaft, and the seriesof worm-gears secured to the duplicate sel-ies of screws, subparte ofthe supplemental deck, and the cover smntially as and for Jche purposespecified. lfoi the open space between the inner edges v 3. The bargeprovided with a Supplemental of the saine, substantially as described.

deck formed in two opposite parts, which have GEORGE N. KENYON. 5 apivot- 01 fnlcruin upon the main-deck at each Vitnesses:
